Most of the low-cost servo amps are for BRUSH motors, not brushless.
A 2-wire DC brushless motor is not generally usable, as it is not
reversible. Don't get gearhead motors, as they introduce backlash
(except for highly exotic motors). Gecko servo drives are for brush motors.

Check outfits like Herbach & Rademan, C&H sales, Surplus Center,
and such.
